NOTE: Always refer to the manufacturer’s service manual for precise torque specifications on

all OEM fasteners.

CAUTION: The exhaust may be VERY HOT — allow adequate time for the system to cool

down before disassembly. Severe burns and injury will occur if skin comes into contact with a

hot exhaust system.

NOTE: This is a large system to remove and install. We highly recommend you grab a friend

to help out with the entire process.

NOTE: Soak all bolts and rubber hangers in penetrating oil before starting any work.

Begin removing your OE exhaust system by first

removing your spare tire.

Next remove the OE heat shield, and hardware

shown in Figure 1 at (A).

Note: This will be reinstalled after you remove

the OE exhaust

Continue by removing the OE dual exit exhaust

by following the steps, shown in Figure 2.

Soak all bolts and rubber hangers in

penetrating oil before starting any

work.

1. To begin you will loosen the OE ball socket

clamp located at (A), enough to separate the

two components.

2. Remove the 5 OE hangers from the exhaust

shown at (B).

3. With the OE exhaust no longer attached to

the vehicle, remove the complete exhaust.

4. Remove the OE tip bezels by removing the 3

bolts per side marked at (D). On each bezel,

all 3 bolts are located on the top side.

Note: The OE tip bezels will not be reused.

Note: After the OE exhaust is completely

removed, re-install the OE heat shield,

and the spare tire.

Once you have ensured that your cut measurements are correct. Cut each side on your mark, and

remove the cut section from the truck.

Note: It is crucial that these cuts are accurate. Inaccurate cuts will affect fitment.

Make sure that the cuts are as straight as possible.

Up next you will need to measure the cut points behind the catalytic converters on the front pipes.

The drivers side cut will be 25/16” from the weld (A) shown in Figure 3-1. Mark your cut point with a

marker.

The passenger side cut will be 23/4” from the weld (B) shown in Figure 3-2. Mark your cut point with

a marker.

IT IS EXTREMELY IMPORTANT THAT THESE MEASUREMENTS ARE

ACCURATE, AS IT WILL AFFECT FITMENT

Now install your AWE front sections (E13) and

(E14) with a 2.5” clamp on each inlet section,

and install them as shown in Figure 6.

Snug the clamps in place, as shown at (A) in

Figure 6.

You want to ensure the outlet of the front

sections are parallel, as shown at (B) in

Figure 6.

Then use a deburring tool on the cut end of the

catalytic converters. It is important that the cut

on the catalytic converters are smooth and there

are no burs or sharp edges, as shown in

Figure 5.

Slide a 3” clamp on each end of the 2 AWE front

sections.

Now put your AWE H-pipe (E15) into place over

the chassis brace for proper alignment, as

shown in Figure 7. The crossover tube on the H

-pipe should be installed over the chassis brace

as shown at (A).

Note: If you are unable to get the H-pipe into

this position you will need to loosen the ball

flange on the front side of the driver side

catalytic converter. This will allow you to

position the H-pipe correctly. Once desired

fitment is achieved tighten the flanges on the

catalytic converter.

Install your AWE passenger side HR5 section

(E18). Slide a provided clamp over the HR5

section, then bottom it in the H-pipe slip fit.

Now rotate the HR5 section so you can slide

the hanger bar into the OE rubber hanger, as

shown at (A) in Figure 8

Note: Snug the clamp but do not fully tighten it

at this point.

Note: It may be helpful to use a pry bar to push

the hanger bar into the OE rubber hanger.

Install your AWE driver side midpipe (E16),

bottom out the short side of the midpipe into the

slip fit. Then rotate the midpipe so the bend is

pointing towards the drive shaft, as shown in

Figure 9.

Note: The angle of this tube may need to be

adjusted for proper fitment further in the

installation. Do not fully tighten the clamp.

Install your AWE driver side HR5 section (E17),

Slide a provided clamp on the HR5 section, then

bottom out the HR5 section on the H-pipe slip

fit.

Rotate the HR5 section so it is vertical, once the

HR5 section is in the correct orientation, snug

the clamp on the midpipe (E16), as shown at

(A) in Figure 10.

Note: Snug the clamp but do not fully thighten it

at this point.

If you have the long wheel base truck, you will

need to install the provided long wheel base

adapters driver side (E42), and passenger side

(E43).

Slide a clamp on each of the preceding HR5

sections, (E17), and (E18). Then bottom out

each adapter section, and snug clamps, do not

fully tighten them at this time.

The rotation of these adapter tubes may

need to be changed to achieve correct

fitment.

It is crucial to install each section and exhaust

band clamps correctly to prevent loose joints,

exhaust leaks and rattles.

Arrow A shows the expanded pipe and the

preinstalled exhaust clamp being brought up to

the corresponding pipe.

Arrow B shows the overlapping pipe installed

correctly over the corresponding pipe.

Arrow C shows the exhaust band clamp being

brought to the edge of the expanded pipe.

NOTES:

• Do not fully torque any exhaust

clamp until the entire exhaust has

been installed and adjusted.

• Torque specification is a minimum of

60 ft/lbs

STEP 12 IS FOR LONG WHEEL BASE TRUCKS ONLY

Install your AWE passenger side axle tube (E20), first place the tube over the axle as shown in

Figure 13-1.

Next slide a provided clamp over the slip joint, and bottom out the slip joint on the HR5 section

(E18), as shown at (A) in Figure 13-2. Then rotate the axle tube to slide the hanger bar into the OE

rubber hanger (B).

Note: Snug the clamp but do not fully tighten it at this point.

Install your AWE driver side axle tube (E19).

Bottom out the slip joint on the HR5 section

(E17), rotate the axle tube so you can slide the

hanger bar into the OE hanger shown at (A) in

Figure 14.

Note: The driver and passenger side axle

tubes need to be parallel going over the

axle. If you install the driver side axle tube

and there is contact with the passenger side

axle tube, then there is an adjustments you can

make. Rotate your driver side midpipe section

(E16) until you have even parallel spacing

between the passenger and driver side axle

tubes. Once the spacing is achieved snug the

clamps down

Install your AWE driver side tailpipe section

(E22). First slide the hanger bar into the OE

hanger as shown at (A) in Figure 16.

Next slide a provided clamp on the slip joint.

Then bottom out the slip joint on the driver side

axle tube (E20), as shown at (B). Snug a clamp

over the joint (B). Do not fully tighten it at this

time.

Install your AWE passenger side tailpipe section (E21). First slide the hanger bar into the OE hanger

as shown at (A) in Figure 15-1.

Next slide a provided clamp on the slip joint, then bottom out the slip joint on the passenger side

axle tube (E19), as shown at (B) in Figure 15-2. Snug the clamp over the joint. Do not fully tighten it

at this time.

Install your 2 AWE quad tip outlets (E33). Use the provided ball socket clamps to secure the tip

outlets, as shown in Figure 17-1, and Figure 17-2.

Note: Do not fully tighten the tip outlet sections, as they may need to be adjusted.

To install the exhaust tips with integrated

clamps, first, attach the exhaust tip in the

proper orientation onto the exhaust outlet tube.

Insert one of the carriage bolts from the

hardware kit (3910-41010) through the tab on

the exhaust tip and thread on one of the

corresponding nuts.

Using anti-seize on the bolt threads will help

installation and prevent breakage of hardware.

Install the exhaust hanger split collar clamps. Use the included hex wrench to help keep the exhaust

system aligned and secure. Install these clamps in the orientation shown at (A) in Figure 20-1,and

(B) in Figure 20-2.

Gather your four AWE exhaust tips, slide them on to the tip outlet sections and orient them so the

AWE logo is facing up. Using the provided integrated clamp hardware kit snug the tips down but do

not fully tighten to allow for final adjustments.

Make your final adjustments to the tips to

ensure they are in a position you like. Once the

desired positioning is achieved, fully tighten

down all clamps.

It is now recommended to drive the car to allow

the exhaust to heat cycle after all clamps and

tips are fully tightened.

At this point the exhaust will be very hot,

allow to cool before work continues.

Check the tips for correct alignment, adjust as

needed.

Don’t forget to see the next page for any

troubleshooting needs!

Once installed properly, your AWE exhaust will provide years of trouble-free performance.

The exhaust volume and sound will settle with usage; 800-1000 miles is required to break-in new

exhaust systems.

Also, please note that the rear 180Technology® resonator has a small drain hole to allow

condensation to escape. Water drops from this area are normal.

Periodic cleaning of exhaust tips is necessary to maintain proper finish, especially in areas prone to

road salt and caustic deicing solutions. Use a mild soap and water solution or car wax to clean the

finish. Avoid using abrasive polishes, as they can scratch the finish.
